I'm thinking about getting a power resistor decade box. I've been looking at older stuff (which is cooler), but I also found a brand new one made by our friends over in China that seems like a fair price.

That one doesn't go very high only 10K. It also doesn't mention what the wattage is for the resistor. I would guess that it has 1/2 resistor in it as does the vintages ones. If you want something that will handle more current you are probably looking at building something.
